Seems this feature means getting call in other media like Bluetooth enabled earphone or taking calls on android auto enabled devices

See if your samsung account linked to other device where you can handle the call or mapped devices.

this feature allows you to receive calls and messages on a Galaxy Tab.
you have to link your tab to your phone by logging in to the same Samsung account on your phone and tab
